Abstract: Inventor:  Richard P. Heintz Title:     "Combined Feedback Control System"     ABSTRACT OF THE DISCLOSURE A combined feedback control system for a servo actuator including a ram that produces a mechanical displacement output of the system as directed by a position command signal. In the combined feedback control system a lever arrangement mechanically combines displacement and velocity information of the ram, and such combined information is conveniently transduced and electrically combined with the position command signal to develop an error signal that controls an electro-hydraulic valve. The latter preferably through a fluid amplification stage controls the delivery of fluid to the ram and, thus, the position thereof. Through the lever arrangement a mechanical failure control is operative to move the ram to a predetermined position upon failure of the electro-hydraulic valve and a manual control is operable to control the ram position via the fluid amplification stage.

Abstract: ABSTRACT OF THE DISCLOSURE        A method for cooking scrambled eggs in individual serv-ing portions or small batches is provided wherein a container is charged with a batch of uncooked, shelled eggs and a plurality of jets of steam and air are injected at spaced, stationary locations into the interior of the batch of eggs to disperse the steam and air throughout the eggs whereby the eggs are agitated and cooked.  While injecting the jets of steam and air the con-tainer is simultaneously and continuously vented to allow escape of steam and air from the container to maintain the interior volume of the container at substantially atmospheric pressure.          Finally, the injection of jets of steam and air is terminated in response to a predetermined condition after the batch of eggs is thoroughly and uniformly cooked to a substantially homogenous scrambled egg mass having an expanded volume.  In the apparatus, a cup-like container is provided for holding a batch of eggs and is adapted to be matingly and sealingly engaged with a cover as-sembly around a projecting cylindrical steam injection conduit.          A disc-like baffle plate is secured to, and concentric with, the injection conduit and is adapted to be received in a free space of the container above the batch of eggs for inhibiting the up-ward spattering of the eggs during steam injection.  A vent pass-age is provided above the cover plate and communicates with the container during cooking of the eggs via an annular aperture in the cover plate concentric with the steam conduit to allow steam and air to escape from the container during cooking to maintain the interior volume of the container at substantially atmospheric pressure.

Abstract: ABSTRACT            The invention relates to apparatus for storing and trans-porting heavy elongate workpieces such as round steel, sectional steel, steel pipes and the like. The apparatus comprises at least two stock racks (1) each of which is formed from two substantially U-shaped girders (5a, 6a, 7a, 5b, 6b, 7b) connected together. A carrying device (3) is also provided for use with a crane in lifting and moving the racks (1).            The stock racks (1) of the apparatus of the present inven-tion are each provided with two suspension plates (9) which are each mounted between the two free ends of the girders (5a, 6a, 7a, 5b, 6b, 7b), and each suspension plate (9) has a part protruding upwardly beyond the girders which is bent inwardly and is hook shaped. The carrying device (3) is  a traverse or beam with at least two pairs of arms (4) for engagement with the hooks of the suspension plate (9). Because the suspension plates (9) bent inwardly the arms (4) do not interfere with racks adjacent that which is engaged by the arms (4). The hook shaped portion of the suspension plates (9) allows engagement between the arms (4) and the stock racks  (1) without manual assistance at ground level.

Abstract: Abstract:          Cereal lipids are useful as an additive to dough in baking bread. It is desired that such cereal lipids shall contain polar lipids, whereas non-polar lipids are not desired. Polar lipids may be separated from non-polar lipids by mixing the cereal lipids with water, subjecting the mixture to gravity separation to form two oily phases and an inter-mediate aqueous phase, and separat-ing the heaviest oily phase which contains the major portion of the polar lipids.

Abstract: ABSTRACT OF THE DISCLOSURE         Improvements in the amount of ore receivable from a seam having an overburden and improvements in mine safety are achieved by strategically deploying inflated bladders for tempor-ary overburden support and using certain bladders as forms for producing permanent support structures.  An access wall is pro-vided to an edge of the seam to be mined by forming a trench or tunnel; and, ore is mined by working into the access wall to pro-duce a series of elongated, substantially parallel chambers.  As each chamber is completed, its overburden is supported by insert-ing and inflating one or more bladders; and, caving of the access wall is prevented by installing a bladder at the mouth of the chamber.  Because of the support, adjacent chambers may be quite close together, leaving only a thin rib of ore therebetween. When the work has progressed along the ore face, the inwardly disposed overburden supporting bladders in chambers remote from the newest excavation may be removed.  The access wall supporting bladders are then filled, or the interior surfaces of the bladders are coated from within with a hardenable composition which is cured to provide a permanent support for the access wall and a dam to pre-vent and control the flow of water or noxious gases, facilitating backfilling of mined areas.

Abstract: ABSTRACT OF THE DISCLOSURE         Method and apparatus for attaching a transducer to an object having characteristics to be measured.  At least two attachment elements each including a number of pointed members are interconnected by a sensing element.          Each attachment element includes a movable wedge member and at least one fixed wedge member whereby initial movement of the movable wedge member with respect to the fixed wedge member subjects said pointed members to a pressure force of a specified magnitude to press the pointed members into the surface of the object.  Further movement of the movable wedge member with respect to the fixed wedge member generates a holding force on the pointed members less than the initial pressure force to hold each attachment element in engagement with the object regardless of transverse forces acting on the attachment elements.

Granted: 1982-08-31
Abstract: ABSTRACT OF THE DISCLOSURE       A method and apparatus is disclosed for bonding two pieces of thermoplastic material to one another.  The method includes the steps of heating the edges of the plastic materials to be joined to at least their fusing temperatures and then forcing the heated edge portions against one another to thereby form a bonded junction.  A bead is formed along at least one edge of the junction of the plastic materials as a result of the pressure of the two plastic materials bearing against one another.  The welded junction is heated, optionally at elevated pressure, to at least its fusion temperature and is then rapidly cooled.  The resulting weld has a high impact and dielectric strength and has a smooth overall appearance.

Abstract: ABSTRACT OF THE DISCLOSURE         An annular valve seat having a resilient metal seal for use in a variety of types of valves provides positive control of fluid flow, with effective metal-to-metal sealing, long life and easy replacement of the seal.          The metal seal is in the form of an annular ring compris-ing approximately one-quarter of a torus that cooperates with the valve's flow control element to establish a metal-to-metal fluid seal which is especially useful at relatively high temperatures.  A first edge portion of the torus is held in position against a radial surface of the valve`s body by a retainer ring which centers the torus about the flow control element.  When the valve is closed the flow control element presses against the outside por-tion of the resilient metal torus forcing the free edge of the torus against a portion of the retainer ring so that the seal is loaded as a structural span supported at the ends by the valve's body and the retainer ring.  The flow control element presses against the central portion of the span which deflects into a concave form to press tightly against the flow control element to effect a fluid-tight seal.  The retainer ring and the torus are held in position in the valve body by a plurality of screws so that the ring and torus may be quickly and easily removed for ser-vicing or for replacement.                               -1a-
